2. Showing things to an audience during a speech is as old as public
speaking. In nearly all cases, showing an audience a physical
thing, an actual object, is the best way to engage an audience’s
attention.

3.  What has been turned upside-down over the past decade’s spread
of PowerPoint, for most PowerPoint users, is that the “speech” is
now mostly what’s on the screen, rather than what is spoken.

4.  1. PowerPoint, when displayed via a projector, is a useful
tool for showing audiences things that enhance what the
speaker is saying.

5.  2. Slides used in a presentation should be spare, in terms of
how much information is on each slide, as well as how
many slides are used.

6.  3. Unless you’re an experienced designer, don’t use the
transition and animation “tricks” that are built into
PowerPoint, such as bouncing or flying text.

7.  4. Above all, use high-contrast color schemes so that whatever is on
your slides is readable. Unless you are a talented graphic designer, use
the templates that come with PowerPoint or Keynote, and keep it
simple—high concept design in a slide presentation doesn’t help in
most circumstances, unless you’re in the fashion or design fields.

8.  5. Rehearse your PowerPoint presentation and not just
once. Don’t let PowerPoint get in the way of your oral
presentation, and make sure you know how it works, what
sequence the slides are in, how to get through it using
someone else’s computer, etc

9.  6. Get used to using black slides. There are few speeches that need
something displayed on the screen all the time. If you include a black
slide in your presentation, your audience will refocus on you, rather
than on the screen, and you can direct them back to the screen when
you have something else to show them.

10.  7. Concentrate on keeping the audience focused on you, not on the
screen. You can do this by using slides sparingly, standing in front of
the audience in a way that makes them look at you, and, if
possible, going to the screen and using your hand or arm to point out
things on a slide.

11.  8. If you show something on a computer that requires moving the
cursor around, or flipping from one screen to another, or some other
technique that requires interaction with the computer itself, remember
that people in the audience will see things very differently on the
projection screen than you see them on the computer screen.

12.  9. Don’t “cue” the audience that listening to your speech
means getting through your PowerPoint presentation. If
the audience sees that your PowerPoint presentation is the
structure of your speech, they’ll start wondering how many
slides are left.

13.  10. Learn how to give a good speech without PowerPoint.
This takes practice, which means giving speeches without
PowerPoint. Believe it or not, public speaking existed
before PowerPoint, and many people remember it as being
a lot better then than it is now.

14.  1. Write a script.
 A little planning goes a long way. Most presentations are written in
Power point (or some other presentation package) without any sort of
rhyme or reason.

15.  2. One thing at a time, please.
 At any given moment, what should be on the screen is the thing you’re
talking about.

16.  3. No paragraphs.
 Where most presentations fail is that their authors, convinced they are
producing some kind of stand-alone document, put everything they
want to say onto their slides, in great big chunky blocks of text.

17.  4. Pay attention to design.
 Power point and other presentation packages offer all sorts
of ways to add visual “flash” to your slides:
fades, swipes, flashing text, and other annoyances are all
too easy to insert with a few mouse clicks.

18.  5. Use images sparingly
 There are two schools of thought about images in presentations. Some
say they add visual interest and keep audiences engaged; others say
images are an unnecessary distraction.

19.  6. Think outside the screen.
 Remember, the slides on the screen are only part of the presentation –
and not the main part. Even though you’re liable to be presenting in a
darkened room, give some thought to your own presentation manner .

20.  7. Have a hook.
 Like the best writing, the best presentation shook their audiences early
and then reel them in. Open with something surprising or
intriguing, something that will get your audience to sit up and take
notice.
